Yeah, it seems that it's only Sa-chan that is after him...
Kagura might be she's slightly too young and I think she's more into Okita, Kyubei maybe a little from 88, but she doesn't really know him, Otae only likes him when he has amnesia, and Otsuu, Matako, Ikumatsu, Mitsuba, and Kuriko are clearly after other characters.
Despite this, personally I think he could go with almost anyone in the series...yay, Gin-san x everybody!

well the point i'm getting at is that almost every girl likes gin-san.I think kagura only thinks of okita as a sparring partner,kyuubei is just shy or afraid that she'll throw him but that was resolved in ep 88,otae is just waiting to see if he straightens out,sa-chan is crazy about him,and if u saw ep 88 u can see that every strange women is always into him VIVA the babel tower heroes

P.S. the swordsman girl from the takasugi arc is also into him,a little

Although most females in the series don't show a romantic interest in Gintoki, I do agree that a lot of females are somewhat interested in him romantically. I wrote this in another forum:

You'll find a lot of guys with "dead fish eyes" much like Gintoki very successful with women. When they actually "try hard" to attain something, they really do "shine". The difference between their usual laid-back state and their passionate state is to women as sugar is to Gintoki.

People are attracted to & inspired by passion. Gintoki definitely has passion when he's protecting those around him. Although most women won't take him seriously because they never "pictured" themselves with someone who doesn't have a real job and will likely never grow up. Only a Kuriko type (accounting her young age) would allow herself to fully fall for someone like that. Sa-chan only fell for Gintoki because of a whole bunch of spontaneous and conincidental circumstances. But the clincher for Sa-chan is probably when she figured out that he actually knew what he was getting into and just really wanted to help her (at the end of ep 22) and Gin told her that if she ever needed him, he will be there.

I wouldn't say that they are after him. The only one that has shown actual romantic interest is Sa-chan. Everybody, (girls and boys) are attracted to him because of his qualities. Their first impression is the same as everybody else: lazy, jobless, rude, etc.. But once you get to know him, and you realize what a strong sense of honor he has. You can't help but be attracted to that kind of person.

It's because he's a lazy dude who still makes the ladies say "weeeellllll maybe.... Yeah I'd hit it" And he gets those points for his seriously ownage on the battlefields! And he's lazyyy and he was like *Kick badguy face!* And they said "OWWWWW" and I said "UUWAAAAH?!" And that's why women love Gintoki!

Well, Otae did for fall him once. Remember the episode when Gintoki lost his memory?
Gintoki said that he would do his best to try to remember her, and she got red, where she then said to forget the past, and start a new future...remember?
And of course the whole Sachan thing, and the girl from the Takasugi Arc, that swordsmith. Did I forgot anyone?
